Ventura's days in charge appear numbered as Italian football bears the backlash of a nation embarrassed by its team's shortcomings, but Insigne is putting a brave face on the situation.

"We're sorry we're not going to the World Cup, it's always a good competition," Insigne told Sky.

"We gave our all to the end but we did not manage it. We apologise to all of Italy, we will do it again next time.

"I have always said I accepted the coach's decisions. He made these choices and I have no regrets.

"It was a game to win at all costs and, for the coach, they were the right men. I have accepted his decisions, it must be done for the national team."

Napoli sit a point clear of Juventus at Serie A's summit and Insigne says the disappointment of missing out on the World Cup allows him to focus fully on securing a first league title since 1990 for his club.

"The Scudetto with Napoli is my goal," he added. "My team-mates and I will do everything until May to make it happen."
